你做这个干什么?用英语怎么说
是
what are you doing that for
还是
what do you doing that for
答
Why are you doing this?
答
为什么不用why？
用what的话该是What are you doing for更合理一点
答
what are you doing that for
答
Why do you do this?
What do you want for?
答
what are you doing that for
因为这个就是问你现在干这个是为什么?强调了目前的行为
答
应该是第二个！
答
问原因不用what,用why更好。
改成：Why are you doing that.
比用what更简洁。
